FDCAN Receive data issue in STM32G0B1RE
Hello Every One!! I am Using NUCLEO G0B1RE Board, facing Issue with CAN Receive Function I am using MICROCHIP CAN BUS ANALYSER and NUCLEO BOARD for CAN Communication void CAN_Recieve(void){ while( (HAL_FDCAN_GetRxFifoFillLevel(&hfdcan1,FDCAN_RX_FIFO0...
I'd like to know to set the TIMx_CCRy? register, I've configured the
I've synchronized TIM3 and TIM4, the TIM4 being triggered when the TIM3 Output Compare No Output on channel 2 is active. I've configured the TIM3 channel 2 as "Output Compare No Output"In order to control the time delay between TIM3 and TIM4 activ...
Read From SD Card gets stuck in a While-Loop (Bug?)
I am working on a custom board equipped with an STM32H753 and a SD-Card connected via SDMMC 4bit wide Bus. FreeRTOS is used. HAL is generated using CubeMX and the package "STM32Cube FW_H7 V1.9.1".CubeMX generates the file sd_diskio.c and in it (line ...
The equation for actual code of internal ADC in SAM4S series of MCUs
I need a clarification regarding the actual ADC code equation for SAM4S family of microcontrollers. The equation from data sheet is,Does this equation hold good for both single ended and differential inputs ?Looks like it is considering a differentia...
How to configure ADC after wake up from STOP (low power mode)
I am using LPTIM for periodic ADC reading (every ~250ms) and periodic IWDG refresh. CPU should go to Stop mode when the ADC value is under certain value. If the ADC value is over certain value then CPU should reset end continue in Run mode. ADC is cl...
Strange ADC behavior
I am working in a project where I have to sample a signal with a sampling frequency of 8 kHz with the ADC. That data is send from the ADC to SRAM using DMA and then send through UART interface. I am using a "Blue pill" board (STM32F103C8T6) with a sy...
Is it possible to run two SDRAM (AP6404L) memories on an L5 OSPI interface?
They don't make DRAM QSPI chips in an SO-8 package with more than 64 Mbits (maps to 2 Mbytes * 32). Given the current processor shortage, I've got an application where I'd like more memory (and I'm using a 100 pin package which is quite pin limited,...
bxCAN time-triggered communication mode not supported
The errata sheet of the STM32F042 states:The time-triggered communication mode described in the reference manual is not supported. As a result, timestamp values are not available. The TTCM bit of the CAN_MCR register must be kept cleared (time-trigge...
Resolved! Why is my GPIO used as NSS toggles randomly during SPI data transfer
Hello I'm using SPI to interface my STM32F7 with the SX1262 radio. I got a weird behavior, I'm using a GPIO to toggle the NSS pin. But sometimes it toggles randomly during the data transfer. You can see on the following screenshot of my logic analyze...
