Thanks Giuseppe You are right about other missing details. The current version of FlowCode is 7.3.0.5 Professional and just now i installed the patch to v7.3 but the problem remains. The graphics card is ASUS HD-6670 with 1GB-GDDR5. The PC is running Win7x64-Pro, CPU is i3 at 3.3GHz, RAM 8GB, SSD 12...

Thanks!

Sure, here the project:

Happy 2018
In the simulation, the first digit of LCD display is always shaded and this applies to all types. However in actual LCD there is not this problem, all digits are printed correctly.
Where is the problem?
Thanks

Why i thought TMR1? Because the load will vary. For example, it will start from 4KW and gradually will drop to 0.5KW. A 4KW load will consume 4000/3600=1.1111W per second or 1/1.1111=0.9 i.e. 1W per 0.9sec. Now we have to change the offset so as TMR1 will overflow each 0.9sec. So, 65535*0.9=58981.5 ...

Happy 2018 :D Now i have to implement an electric energy consumption counter in KWh, similar to this installed in our home by the electric company which can count up to 99999.9 KWh and then rolls over to 00000.0. It increments by 0.1KWh. Let's make some calculations: A 3600W load connected for 1 hou...

And yes, it works on actual hardware

OK, i found the way to discard the fraction part of voltage and power, and to have only one fraction digit for current indication: It remains to verify on actual hardware.
Many thanks again

Hi Christina Yes, you got me. For mains voltage reading (230Vac nominal) actually i need only the integer part for the LCD, the fractional part will be discarded. For current reading i need the fractional part for LCD but up to 1 digit, e.g. if is 12.43 i only need 12.4. For Power indication i need ...

Hi How could we convert a non-integer (float) with 1 or 2 digits in fractional part to string? What i need is to print e.g. the number 17.4 or 17.45 on the LCD. This process is included in the ADC component, e.g. you could select "ReadAsString" and the non-integer value will be printed with two frac...

Hi Graham The attached fcf simulates the operation of a detent equiped encoder. Is this: http://uk.farnell.com/alps/ec11e18244a5/encoder-vertical-11mm-36det-18ppr/dp/2064993?ost=2064993&iscrfnonsku=false&ddkey=http%3Aen-GB%2FElement14_United_Kingdom%2Fsearch This type is more complex compared to non...

Hi I will setup a PIC as slave in I2C bus with a 7 bit ID. I came across the Microchip datasheet and from what i understood, for a slave to respond in a unique ID all bits in Slave Address Mask register must be set to 1? E.g. if i want the slave to respond only in device address (or ID) 0x30, the Ad...

Hi I came across EB006 programmer datasheet and in the list of supported devices the familly of P18F26-27-46-47J53 is not included. Why this? Within FCv5 and FCv7 are included in the target device list. Is simply an issue of the package as all are SMT type? In this case the ICSP header could be used...

Thank you Steve. Regarding myself there is no problem. I'm not so willing to get into a debate with Parts Connexion. I haven't neither time nor the physical strength for it as i suffer from CAD (coronary artery disease). On the other hand, such actions should be mentioned and denounced as insulting ...

Hello to all Two days ago, i discovered that the code is probably used for commercial purposes by a company which sells an identical kit like the project of this thread. Here the link http://www.partsconnexion.com/kits_remote.html The instructions in the user manual of this kit regarding the initial...

Thanks for your reply! In the mean time, I manage to alter your original flowchart with RC5 component and its working ok! Hi! I want to make a remote control with 6 buttons and I chose pic16F1828 too but my program doesn't run! I post my fcf file and please, when you have time, to correct my code. ...

Hi there! I want to make a remote control with 10 buttons. For this, I chose pic16F1828 because that has 10 IOC. All well and good, but I can not manage to alter your code for my needs ... I post my altered version for the 16F1828 and please, when you have time, to correct my code. Regards, Puiu! H...

Jan i think you need a fully RC5 compatible remote control handset. It is not only the period, it is also the transmition protocol structure. An RC5 transmiter transmits: 2 start bits for AGC of receiver, 1 toggle bit, 5 address bits and 6 command bits. There are enough compatible handsets on e-bay ...

Hi Ben My intention is to produce 3 individually activated pulses to drive 3 relays. Using 3 TMR interrupts to this could cause side effects. So i did some calculations to use 3 of the 5 CCP modules provided by P16F1939. The coil of relay must be powered for the less possible time so as to consume t...

It works.
Thanks fellow from hot Arizona!

Hi I use a P16F1939 with Fosc=4MHz (internal module). I do like to configure three CCP outputs of it (it offers up to 5) to produce 3 PWM (or pulse streams) with period=15msec and duty cycle=33% (or ON=5msec and OFF=10msec). Using the PWM component provided by FlowCode i can obtain a max period=4mse...

OK fellow, since you persist on it, here is the - incomplete - fcf till now.

My LCD is 16X1. Here a picture how it prints in 8X2 configuration. Attached is the datasheet.

Spanish_dude wrote:Have you tried just keeping the configuration at 16x2 and only writing on the first line ?

Yes, i tried the 16X2 configuration but again the same problem, only first 8 characters are printed.
Thanks friend by anyway.

Hello I bought two 16X1 LCDs, one cheap from e-bay and one expensive MIDAS with large characters from Farnell UK, both compatible with Hitachi HD44780 controller. If are configured in FlowCode as 16X1 only the first 8 characters are printed. If are configured as 8X2 then with proper calculation of c...

Yes, you are right. PPP i use is the latest version, simply i didn't noticed the "Clock Out Enable bit" on config table.
Thanks by any way.
