Hi Christina, If the encrypted string contains NUILL characters then you may need to use a byte array instead of a string, a NULL would effectively mark the end of the string. Otherwise a string should do exactly what you need it to. The print as hex is likely just done by the console or whatever yo...

I've been working on the W5500 support for the network comms component today and though I've fixed a number of problems it's still not working 100% nicely for me. I've pushed the various changes to the update system so you can see if it's any better for you now. Here's my project file. NetworkComms-...

Hi Christina,

Many thanks we will investigate what might be causing this.

Hello, To discount anything in your program causing the problem can you disable the other code or at least add a while 1 loop so that it enables the interrupt and then loops forever in main without doing anything else. I'm thinking maybe an ADC read on that pin or something else similar is maybe swi...

Hello, First we try the calculation using the high speed baud rate, this gives higher resolution so will be able to acheive faster baud rates with less error. If the calculation results in a value that is too big for the baud rate register (> 65535) e.g. a fairly low baud rate then we switch to the ...

Hello,

Working fine for me.

Here is a Flowcode project to receive the data from the USB Serial Component.

Just set the correct port for the COM Port component, then click run and it should receive the data.

Woohoo,

Excellent, sorry this was so long in getting to you and really happy this is working correctly now.

Thanks for bearing with and letting me know.

Hi Stefan, The baud calc is done here in this file which also references the project options clock speed. C:\ProgramData\MatrixTSL\FlowcodeV8\CAL\PIC32BIT\PIC32BIT_CAL_UART.c If no dividor is specified in the device definition file then we currently default to 4. #ifndef MX_UART_BAUD_DIV #define MX_...

Hello, These PIC32 devices are very odd, some work fine but others do not and the rules seem to change mid family so rolling out a divider is very hard. I've tried multiple times to get this right. Which PIC32 device(s) are you currently testing. I could maybe change the UART baud calulation for the...

I'll put together an ESP8266 example for you.

In fact I might do various examples as this will allow me to proove to myself that things are well supported and working.

Hi Dave,

I had a look and didn't spot anything obvious. Have you tried the timer component to see if that will do what you need?

Hi Monie,

Have you tried the component I highlighted in the screenshot - LCD I2C (LCM1602)?

This has the PCF8574 code built into it. If this isn't working then do you have any example code to work from that I can compare with the component.

Thanks Martin,

Third time's the charm (hopefully)

Hello,

I beleive the W5500 is fine and also the ESP8266 should be ok too. I'll double check these now.

Hi Martin,

Wow thanks for getting back so fast. I beleive I have now found and fixed the problem for you.

Hi Dave, I've just looked at the code for the ADC on the K22 devices and it looks to be ok. The ADC component in your project is pointed to AN0 though I'm guessing this isn't the cause of the issue. Maybe try a conversion rate other then the FRC setting. Might also be worth getting rid of the C code...

Hello, The ENC28J60 component is not supported by the Network Comms component at the moment. Just looking into this now for you but it looks like it may be hard to impossible to support the ENC28J60 module with the Network Comms component as the ENC28J60 module exposes a lot of the lower layers that...

Hi Stefan,

Excellent glad it's working well for you now and thanks for letting us know.

Hello Ralf, Just looking into this for you and the ADC code looks ok. One thing I spotted is that there is a digital input disable register mentioned in the datasheet. It doesn't say it is required to be set for ADC conversion but it's work a go. DIDR0 = 0x3F; //Disable Digital Inputs DIDR0 = 0x00; ...

Thanks for the suggestion.

I've added the info to the wiki page now.

Hello,

Can you post your Flowcode project file and we can investigate for you.

It's worth checking your config and clock speed are setup correctly so the best way to do this is to do the 1 second flash test.

Hi Martin,

I've had another look into the problem this morning and pushed a change to the device definition files which hopefully solves the problem.

Thanks for chasing this one up.

Hello,

If everything is delimited with a full stop then I would do something like this using a finite state machine approach.



You might need a timeout to reset the RxMode back to 0 if no data is received for several seconds.

Hello,

The Connection type property allows you to select if the display is serial, 8-bit or 16-bit.

The Data[7:0] and Data[15:8] properties allow you to specify the port connections.

Or if you change the Use Ports property to No then you get individual pin properties you can set.

Hi Monie,

It looks like that display uses the PCF8574 IO expander to drive it. So you will likely need to use this component instead.



I beleive the backpack component uses the MCP23017 IO expander instead.
