Resolved! Adding a LF to a string of unkown length
Hello Everybody,I am wondering if this is good code when using an embedded system or if I should avoid adding a LF to an unkown string like I do it here, since this could overwerite other data in the following address:void USART_transmit_message(vola...
Resolved! STM32H743: sprintf not working in newlib_nano after upgrade from HAL 1.3 to 1.6
Not a question but a statement. I've just upgraded a very large project from HAL V1.3 to V 1.6. The code uses sprintf in a couple of places. This worked fine under 1.3 using newlib_nano. Under 1.6 the same statement gives a NULL return. Swapping to n...
Few packets are getting missed while reading byte by byte using HAL_UART API's
Hello All,I have configured UARt for Rx interrupt and in the ISR I am reading the UART byte by byte and sending the same to my terminal using HAL_UART_Receive and Transfer API's.But if I use HAL_UART API's, few bytes of my data is missed in middle an...
RM0394 Rev 4 duplicated pages
In RM0394 Rev 4, pages 193 and 194 are identical, this is probably not intended.So, there is really absolutely no proofreading of the RMs before issuing? I mean, this is hard to overlook, even if it would be a non-technical person doing it.JW
Resolved! Internal temperature return wrong value
HiSo I''m trying to use the internal temperature sensor to get a rough idea of the temperature. So first I test it on the NUCLEO-F446 and get good result but when I try to use the same code on my board, I get wrong data. Good data is adc value aroud ...
Why the EN flag bit in DMA_SxCR register is cleared when I powered up the peripheral device? I have linked DMA with UART for receiving purpose only.
I am using Nucleo-F429ZIT. I have used UART4 and linked it with DMA for reception. The EN flag bit in DMA_SxCR register is cleared when I connect peripheral board with STM. This issue is happening only when I disconnect the power supply of peripheral...
I am using CAN Communication between two STM32F429ZI Microcontroller i am not able to receive the Interrupt callback HAL_CAN_RxFifo0MsgPendingCallback() after receiving the Transmitted Data.
I am using this Flow for Transmitting Data and Receiving If Anything I am Missing From Flow of Execution wise i am not getting Receiver Callback. filterConfig.FilterFIFOAssignment = CAN_RX_FIFO0; filterConfig.FilterIdHigh = 0; filterConfig.FilterId...
STM32G070CB Internal ADC1 Not Reading Zero when PA0 Connects to GND
Hi ST Community!I am new to the STM32 family of processors and have recently attempted to make a personal board that houses the STM32G070CBT6 controller.One of the features I have on this board is the ability to measure the current via a TI INA181A1 ...
Nucleo-L476 doesn't get recognized !
Hi ,I started with the step by step learning program. Installed several software packages and tried my first task in truestudio. However, my Nucleo-L476 doesn't get recocnized. Probably because there's Mbed on it??? How can I get it recocnized?I did ...
