Posted on July 13, 2016 at 18:24hello sir.my project write SD card error, but it read SD card properly. when I debug into code, I found __HAL_SD_SDMMC_GET_FLAG() in HAL_SD_WriteBlocks() function always get error flag SDMMC_FLAG_DCRCFAIL. and it writ...
Posted on July 14, 2016 at 16:49 Hi, I use a STM32F205RG6 chip and splitted the flash into 2 parts, 512K for the program and 512K for user's data: MEMORY { FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 512K DATA (rwx) : ORIGIN = 0...
Posted on July 14, 2016 at 08:43 Hello, I want to generate pwm out through tim4 channel 1 This is the code, but isn't wokring void hw_init_timer_4(TIMER_INIT* _tim4) { GPIO_InitTypeDef gpio_init; RCC_ClkInitTypeDef clkconfig; TIM_...
Posted on July 14, 2016 at 04:49Hi: Are there any documents mentioned about chip selection for upgrading from STM32F4 to STM32F7? I find a document AN4660 talking about migration, thus I know STM32F756 is the candidate. However is there any table ...
Posted on July 14, 2016 at 23:40I am using Keil. How should one determine what is the best size for the heap and stack? Are there any common guidelines? Thanks.
Posted on July 14, 2016 at 22:41 I'm attempting a fairly standard initialization of the SPI peripheral on an STM32F302, and for some reason whenever I call GPIO_PinAFConfig(GPIOA, GPIO_Pin_15, GPIO_AF_6), the program jumps to the WWDG_IRQHandler...
Posted on July 13, 2016 at 23:21So, the Cortex-M0 doesn't support tracing (so it doesn't support semihosting). The board has a TX & RX pin and a corresponding pair of solder bridges, but the manual says ''reserved''. So is it best to connect an exte...
Posted on July 14, 2016 at 17:27 I'm using an STM32L151 board and I want to know how to map a memory address to its function. For example: LDR.W R0, =0x20002A20 MOVS R2, #4 MOVS R1, #4 STR R1, [R0,#0x14] LDR.W R1, =0x20002224 STR.W R2, ...
Posted on July 13, 2016 at 14:31Hello, the HAL function HAL_CAN_Transmit_IT() enables the Transmit mailbox empty Interrupt before the requesting transmission. At least if I run the CAN bus wit 1Mbit the mailbox empty interrupt is triggered before th...
