Resolved! Is there any difference between “stm32f100c8t6b�? and “stm32f100c8t6�?？
I can find some difference from datasheet,The definition of B is "internal code".But there is no further explanation.

Resolved! Inconsistencies with every HAL_SPI_Transmit() of the same message
Am getting inconsistencies with every HAL_SPI_Transmit() of the same message in a for-loop. Viewed the result with a logic analyzer and the results are frustrating.Am just trying to send a Hello World! but on the Logic Analyzer, am getting dummy data...
Resolved! Issues with I2C - Gives HAL_ERROR for the VL6180X distance sensor
Hi!I'm was writing C-code for the VL6180X because I find ST's own C-code library quite messy and I could not use it because I did not understand it. So I re-wrote a C++ library to STM32 C-code from https://github.com/pololu/vl6180x-arduinoHere is the...
stm32g474 qspi do not work
when i use HAL_QSPI_Receive() in debug mode, always "internal command error". I found this MODIFY_REG(hqspi->Instance->CCR, QUADSPI_CCR_FMODE, QSPI_FUNCTIONAL_MODE_INDIRECT_READ); will cause the error. but i do not know how to correct。
DAC and PWM won't give out current - Why?
Hi!I'm trying to enable DAC and PWM so they can give out current, but nothing happens. I have tried to connect a simple LED to the pin, but non of the DAC nor PWM pins light up the LED.First of all, here is my init for TIM2, which has PWM enabled.I e...
CAN interrupt not fired after one reception of data
In stm32f042g6 CAN rx Interrupt is not fired requently,How i will reset the interrupt flag so it will receice data frequently on interrupt?i am facing FIFO0 overrun error (CAN process is ongoing )How to overcome this error to receive the data frequen...
I need to know the lead time for these two STM products? STM32H743VIT6 and STM32F103
We are designing a control board by using STM32H743VIT6 and STM32F103C8T6. But there is no stock available for these two STM products in any electronics part suppliers. Without these parts, we could not move further with the designing process. Theref...
Resolved! [STM32F373] I/O characteristics - Schmitt trigger hysteresis details
Hi!I measure the frequency signal on the input of STM32F373. General Purpose Timer in Input Capture configuration is being used to do so. But when the rising edge width of the input signal is around 110 ms, I detect some extra, unexpected pulses. I s...
Resolved! MEM_MODE resets to 0x00 e v e r y t i m e (stm32f072)
I want to move the isr vector table to SRAMRelated to this questionI moved my isr vector table to SRAM (linker script)Now i want to aliase the memory addr of 0x0000 0000 to be found in SRAM.In order to do that i believe i need to change the bits from...
Hi, I am using STM32H7A3 Nucleo Board. I am using HAL_UART_Transmit() to transmit UART data and HAL_UARTEx_ReceiveToIdle_DMA() for receiving data.
Is the below calls are required between every transmit and receive call, if we are using DMA? if(HAL_UART_DeInit(&UartHandle) != HAL_OK) { Error_Handler(); } if(HAL_UART_Init(&UartHandle) != HAL_OK) { Error_Handler(); }Please give a clarificat...
