UART/RS485 multiple Devices with MAX485

Hey everyone :) I'm using some Bluepills with a STM32F103C8T6 and a Custom made Board also with a STM32F103C8T6. The custom Made boards communicates with the Bluepill Board. I'm using a Max485 UART/RS485 Transceiver. This Transciever has an Enable Pin which needs to be High to send data and low to r...

Re: Porblems with HID Bootloader

Hey guys,

I used another PC to try it again and it works - seems to have something to do with my notbook.

Re: Porblems with HID Bootloader

Hey, sorry - I should have known that this have been not enough informations. I'm using a Bluepill Board with STM32F103C8T6 Processor on it. The bootloader was programmed with stm32Cubeprogrammer. Upload is done in the Arduino IDE. And I'm using the official core from https://github.com/stm32duino/B...

Re: CH32F103C8T6 China chips

hey,

thank you for your reply and the informations!
But there is still the question about the bootloader right? or do I have to interpret this as a "no"?

Greetings!

CH32F103C8T6 China chips

Hey guys, I had some problems using the HID Bootloader. (using ST Link to programm works fine. Serial.println() as well) After flashing the HID Bootloader the board wont be recognized. Also with Boot1 pin HIGH. What I found out is, that I got some Boards with a fake processor called CH32F103C8T6 fro...

UART speed

Hey guys, I would like to speed up my UART communication. actually it looks like this: K800_UART_Timing_02.JPG I would like to increase the time between the bits where nothing happens. I'm using a Bluepill Board with the offical core. My Code looks like this: #define SAMPLERATE 2000000 HardwareSeria...

Re: Use STM32 as I2C Slave with DMA

Hey :) thank you for your reply!
I think, that goes beyond my programming skills...
Is there a plan to implement this feature?

Re: Use STM32 as I2C Slave with DMA

I'm still a little bit confused by the cores, but it should be the official ST Core from https://github.com/stm32duino/BoardMana ... index.json

Use STM32 as I2C Slave with DMA

Hey guys :) I had an working system with an raspberry pi Master and an STM32F103 slave which collects data from other slaves via another I2C bus. I have done over 6000k measurements. I just added a few temperature sensors and it kills a lot of timing. To overcome this problem, I would like to use DM...
