Re: I2C communication with SAA1057

Hi there. I'm sorry I've no time currently to help in any detail, but a quick glance at the datasheet confirms this chip doesn't actually employ I2C at-all. All you're doing is clocking single bits into a 16-bit wide shift register (repeated to successively program Latch-A and Latch-B), so you shoul...

Re: I2C communication with SAA1057

I understand and empathise... If you can follow my first example, I'm sure things will quickly click into place :) Think of a string of 1's and 0's just typed on an old-style typewriter, where the amount you temporarily move the carriage to the right is decided by the value in LoopCount, and the bit...

Re: I2C communication with SAA1057

So in total i have to send 2 bytes for the first wordb, 2 more bytes for the worb again and then 2 more bytes for wordA, this should initialize the chip. Yes, I believe that should do it, though haven't studied the datasheet in any depth as I'm presently working on an urgent consumer project. Then ...

Re: I2C communication with SAA1057

Hello Again. First, your data is looking considerably better now that you've slowed things down :) I've taken a quick look at your code and my first advice is to get rid of the decision operator and connection points in order to exit your loops. Connection points , while 'OK' in many instances, are ...

Re: Sending Hex value with RS232

Hi Rob. I do lots of stuff over RS232, though I'm not sure I understand your question. To clarify, I trust you're declaring hexadecimal appropriately (0x..) ? Fundamentally, the question is largely how you intend to process or view the data at the receiving end. For example, if I were using a progra...

Excellent news.

Thank you for the confirmation, and I've no doubt your discoveries will be of future assistance :)

Re: Test Based Applications - Have your say

Hello FC team. I have suggested this elsewhere, though relevant to this thread in particular... Due to our successes using Flowcode to develop bespoke, portable, standalone test rigs, we're now integrating large capacitive touchscreens and FTDI's "Vinculum-II" chipsets into the mix. This w...

Re: EB091 USB

Hi Ben So you can either return the board to us and we will apply the fix or you can apply the fix yourself. I will make sure that the up coming batch of EB091 boards are corrected so USB will work straight away. There was also a minor Flowcode definition change to alter the USB prescaler and allow ...

Re: Is your Project Not working? Help and General Advice

Hi. Without sight of your code, I can only flag a few pointers which may or may not be of help... Instead of manually stepping through the code, let it free run but slow stepping right down to perhaps 1s per step. Then, while running, click and hold the pushbutton throughout the complete simulation ...

PROBLEM SOLVED: Working with Parallel SPI...

First, a huge 'Thank you' to afficianado Kersing, who kindly presented me with valuable direction on the subject of directly messaging Flowcode over USB from Linux, to negate the requirement of third=party USB-Parallel interface for high-speed transfer of data. Given the number of hits this topic ha...

Re: FC7 issues - SPI and zoom

Hi Leigh. Thanks for the confirmation. I can say that Pladnows checks confirm that 32MX and MZ chips are affected, so common across a range of devices if this helps (we haven't checked them all). Please let me know if this is likely to take time to resolve, in-case we should need to workaround befor...

CRC calculations leveraging MCU hardware engine

A CRC calculation component (particularly leveraging hardware CRC engines where provided) would greatly assist with coding and operational efficiency, and add significant value for advanced/professional PIC users - particularly high-speed 32-bit devices where FC7 holds key advantages.

Re: Support for some kind of large screen

A big thumbs-up for 4D products from me too. We've used their 4.3" capacitive touch displays for stand-alone test equipment featuring VI's and touch keyboards. Their Picaso processors (and faster Diablo if needed) are just the ticket for working with small MCUs as they off-load screen driving r...

Re: Help with 12 volt battery variable voltage supply please

For the record, you might also like to consider a voltage-controlled (active) current sink in a regulator's feedback circuit, where PWM voltage (amplified by an op-amp for stability and offset correction) leaches current from a feedback arrangement. Imagine an N-channel MOSFET with source to ground ...

DMA Channeling

Furthering the power of Flowcode 7, itself supporting 32-bit micros with extended hardware features, I'd like to throw in DMA Channeling: My rambling thoughts suggest a DMA component, enabling the user to individually nominate DMA channels afforded by the device for hardware-driven data piping direc...

Re: 32mZ UART Flow Control Pin Selection

Hi Ben. The device concerned is PIC32MZ2048EFG144, and no bootloader. It's a bit of a handful, and we're progressively getting to know it better, though appears to set itself apart in the way you have to configure and use it. Other things seem not to make sense, such as growing silicon errata (the '...

Hardware UART component - PIC32MZ... [Solved]

PIC32MZ continued... I'm sure they could make a soap opera of this chip, but a recent personal observation when attempting to enable hardware UART. In simulation all is good, but the problem reveals itself at build time. To confirm, I'm working with PIC32MZ2048EFG144, using the latest Flowcode V7.1....

Muxable External Interrupts for PIC32MZ...

Hi Ben. Many thanks for the recent updates, with 'FC7_Latest_Files_051216' patch downloaded and applied. I noticed an issue however with pin-selectable external interrupts (specifically, for the 32MZ2048EFG144 chip that we're using). I'm setting up to monitor 20 x system fan tachos, organised as fiv...

Thanks Ben.

I can confirm download and use of the PIC-specific update, with all associated pin-selectable options present and correct. Furthermore, muxed bank select table created in the flow, and the project builds successfully :D

I'll update all to the latest zip.

Re: Analogue Interrupts (IOC)

I can sooo relate to Ben's 'key points'. I've started off being 'too' clever with unnecessarily modular code (with many macros) in the past, only to sorely regret doing so as the code developed with later changes necessary. On one occasion, it got so confusing that I threw the source away and starte...
