STM32G030 DMA to GPIO BSRR bus error
HiSTM32G0 series is a newer chip family with more advanced DMA/MUX to provide more flexibility.my code, which uses tim16 update to request DMA to transfer from memory to GPIO BSRR. The code works on STM32F030 but fail in G030. The request from TIM...
STM32L476JEY generates RX overrun error when using DMA to read from SD card
I am using STM32L476JEY MCU. SDMMC works fine at 4 MHz clock speed with interrupt enabled and DMA disabled. However when I use DMA to read a block it generates Rx overrun error. When I checked the output buffer it read 4 bytes instead of 512 bytes.I ...
STM32F732 BOOT1 pin
I thought the BOOT Modes used BOOT0 & BOOT1(PB2) pinsand to pull BOOT0 (high) and BOOT1(low) to get BOOT MODE (SYSTEM MEMORY) and allow the STM32CUDE programmer!I've looked thru the STM32F723 Docs and PB2 does not seem to show/sharethe BOOT1 pin func...
Single bank mode for STM32L471RxE devices
Hi EveryoneI'm having some trouble with the reference manuals description of single bank mode for the STM32L471RxE devices. In the attachments you can see that the page number for bank 2 always starts with 256, regardless of the flash size. What I co...
Unwanted NMI interrupt of CSS peripheral of stm32G491CC
Good morning community,I am contacting you to ask for support regarding a EMC immunity problem I'm experiencing.My application uses an stm32g491cc MCU with an external 8 MHz ceramic resonator (HSE)What i observe is a reset of the microcontroller duri...
How to fix the I2C slave issue with STM32G070? HAL_I2C_ListenCpltCallback, HAL_I2C_AddrCallback, HAL_I2C_SlaveRxCpltCallback, HAL_I2C_SlaveTxCpltCallback
Hi, I'm trying to setup a stm32g070kb (32pin) MCU as I2C slave by using CubeIDE.I would like to create a code which will work same as I2C Eeprom, but when I ask the stm32 (with another MCU) to return me a register or registers value, the returned reg...
STM32C0 Boot Programming
Hi, I am planning to use STM32C011F6 for a simple application and want to download application through UART1. How to use BOOT0 pin to program MCU for the first time. According to data sheet, UART1 pins PA9/PA10 needs remapping to function as UART. Al...
Resolved! [ STM32G070 ] STM32G070 input mode pin speed setting?
Dear Sir,In STM32G070 series, the code shows the speed setting for GPIO output,If my GPIO is setting for input to receive external interrupt, does the speed setting also apply for GPIO input mode?Thanks/** @defgroup GPIO_speed GPIO speed * @brief ...
SDIO API for H7
Sorry, I am new STM32 MCU :grinning_face_with_sweat: I want to bring up WIFI function with SDIO to connect Internet, but I cannot find any SDIO API in H7 like stm32f4xx_sdio.c.The link is where I can find the answer I want, but it only supports H747...
