Re: 2x WS2812 Components Don't Work

Hi Ben, Thanks for your lines! We can't daisy chain any of the LEDs, they are totally separate PCBs (some of them using WS2812 LEDs, others using WS2818 drivers) with their own PSU and go to physically opposite places for different parts of the system. This was not a problem with FC9, FC8 before :-(...

2x WS2812 Components Don't Work

Hi there!

Simple setup. ESP32 Chip.

1x WS2812 Component with 2 LEDs works fine (Output A27). If I add a second WS2812 Component with another 2 LEDs (Output A26)

None of the LEDs work at all :-(

If I remove the first WS2812 Component, the second works fine.

Thanks for your help!

Re: STM32F0 ADC and FC working at the moment?

Hi Steve,

Many thanks for this! It does help indeed very much.

The STM32 devices are so cheap these days that we are using them as I/O expanders, so only UART, general GPIO I/O and some ADC, maybe timer as well.

Thanks again for the prompt reply!

Regards,
R

STM32F0 ADC and FC working at the moment?

Hi guys, I've used PIC and ESP32 so far with Flowcode, very happy with it, pretty much everything works well... I'll be using STM32F0 soon... and was wondering if ADC is working at all in Flowcode? Furthermore, what things aren't really working well in Flowcode on STM32F0? Thanks in advance for your...

Re: STM32F0 I2C Slave Support

Hi Ben,

Thanks for your answer! No problem at all, I will adapt to use RS485, it's very easy to do and just need a cheap transceiver...

So all fine and thanks for the swift reply.

STM32F0 I2C Slave Support

Hi everyone, Can someone clarify please if Flowcode 9.x supports I2C Slave (in hardware mode) on STM32F0x devices? We would like to have 2x STM32F0x MCUs on the same I2C bus acting as I2C Slaves (with 2 different Addresses) and we were wondering if Flowcode supports this configuration. More importan...

Re: I2C Call Inside Timer Core Dump ESP32

Hi Stefan, I think implementing tasks indeed... I was thinking that whatever code runs at the moment on ESP32 given the nature of things is on Core1 (from documentation I've read - I am not a programmer). So at least maybe a possibility of starting a task within Flowcode on the other core would be g...

Re: I2C Call Inside Timer Core Dump ESP32

Thanks Martin, It won't crash, cause the Call is inside the Interrupt. I have found an excellent answer to this question. I just need to get my head around this and think how to re-engineer my mind as I come from the PIC background and new to ESP32. But anyway, it's a good read and makes total sense...

I2C Call Inside Timer Core Dump ESP32

Hi guys, I've got a very simple program whereby I update an I2C device periodically once a second via an interrupt (Timer0). This is causing a core dump and I am not sure what else to try here, I've reduced the program only to the I2C and the Timer routines and means all my other peripherials are no...
