Posted on July 28, 2016 at 14:03For the last few months I've been working on a project that used an STM32F030 microcontroller. Due to a shortage of GPIO I've had to use the SW debug pins for other functions. Until recently this wasn't a problem, sin...
Posted on April 26, 2016 at 17:00I've got an STM32F0 based I2C slave device which I'd like to send simple commands to, as well as updates containing additional bytes of data. HAL_I2C_Slave_Receive_IT() seems to require you to directly set the number...

Posted on August 27, 2015 at 13:08Hi,I've been looking over an example of master/slave I2C communication using an interrupt and I just can't seem to figure out how it actually works. The description is really vague and the HAL documentation isn't mu...

Hi all,
I've been getting familiar with the RCC stuff on the STM32L152 (STMrecently152L-Discovery), but I'm struggling to push the baud rate of my USART transmission beyond 130Kbaud.
I've set u...
Posted on July 28, 2016 at 15:43What could be causing this in my code though?I thought the whole point of 'connect under reset' was to allow the device to be programmed even if you used the SW debug pins. That way the programmer, through access to t...
Posted on July 28, 2016 at 14:57Except for many months before this it has not been an issue, so clearly using Boot0 is not the only way. From my understanding, connecting under reset (and giving the programmer access to the Reset pin) had allowed t...
Posted on April 26, 2016 at 16:51Did you ever find a solution for this?I've been looking, and the only way I think you might be able to do it is by assessing first byte and then polling for the remaining bytes afterwards in the I2C ISR...? If you ev...
Posted on August 28, 2015 at 12:36This is for an STM32F030F4P6The example I looked at was one with the STM32CubeMX pack for the STM32F030 family nucleo: ''\STM32Cube_FW_F0_V1.3.0\Projects\STM32F030R8-Nucleo\Examples\I2C\I2C_TwoBoards_ComIT''Firstly ...
