Posted on July 10, 2018 at 15:54 Hello everyone, I want to connect one LM5066 to a STM32F072 (currently a Nucleo) via the provided SMBus/PMBus. Unfortunatelly the configuration and daata transmission seem to be very different from I2C, that I ...
Posted on July 09, 2018 at 21:26 I've been experimenting with writing to an external https://www.microchip.com/wwwproducts/en/93LC46B using SPI and I've had mixed success. The data does get shifted out but in an opposite manner. The EEPROM req...

Posted on July 08, 2018 at 16:35RM0091 Rev.9, 30.6.2 Buffer descriptor table, states:The packet memory should be accessed onlyt by byte (8-bit) or half-word (16-bit) accesses.Halfword access is OK. Bytewise read is OK. But writing a byte results in ...
Posted on July 06, 2018 at 16:02This flag should be forced disabled in CubeMX because there is a known bug in FreeRTOS prior to v.10 leading to an out-of-bounds write and (kernel) memory corruption. Must not be used prior to Freertos 10.0.0.#tcb_t #...
Posted on July 04, 2018 at 05:13 Hello guys. I configure the CDC on CubeMX. But the function CDC_Receive_FS receive1 byte each. That is, if I transmit 12345678 then I receive only 8. I have to modify the function like this: uint8_t UserData...
Posted on August 07, 2017 at 17:32 Hello, I am getting UART errors (by the means of the HAL_UART_ErrorCallback callback function) but the strange thing is that the value of handle->ErrorCode is zero! So, an error but no error code. I think there ...
Posted on July 05, 2018 at 08:10Hi everyone, in my system (freertos based) i need some low pulse before sending uart datas. So i must change tx pin to gpio and send low pulse along appx. 100uS and after that i must rechange it to uart fastly. How ca...
