I am developing a serial comms protocol between two STM32F407s.I am using the hardware CRC module to generate checksums for some of the data.I am also writing a test script in python to aid development.All has gone well until now.Now I need my test s...
I use STSPIN32F0 since over 2 years. In the last assembly I have a problem with wrong AD values. So SW is in the older and in the newer hardware equal. The problem is so strange.Attached is the schematic of Keypad Input which is connected to PB1 (AD9...
Figure 365. "Frame transmission in MMI and RMII modes" of RM0090 shows the low levels on the RMII outputs in the idle state. Is this guaranteed?
I have a requirement to design IAP bootloader for STM32F427 based custom board. Can we design such an IAP bootloader which will communicate to DFuse tool using the same windows drivers provided by the ST along with DFuse Software package. I have trie...
Hi.I am using the STM32746G Discovery Board and running the STemWin which uses the external SDRAM [Part No.: MT48LC4M32B2B5-6A, Manufacturer: MICRON] to buffer the LCD rendering. Is it possible to use this external SDRAM to store program variables in...
Hi there,i wondered if it's possible to support more than two composite device classes. I am using stm32f407ig and in the reference it says there is a control endpoint 0 and it supports 3 IN/OUT Endpoints. So it must be possible to implement CDC+HID+...
I am trying to use Timer Output Compare on STM32F746NG with the following code:void TIM1_CC_IRQHandler(void) { volatile uint32_t a = TIM1->CNT; printf("DUMMY\r\n"); } void timer_start(void) { TIM_HandleTypeDef htim1; TIM_OC_InitTypeDef tim1...
Hello,I am using timer as stm32f401.However, the clock set in CubeMx is different from the actual clock. (I set it to 48Mhz, but I get 2Mhz when measuring with an oscilloscope.)I used the MCO pin to measure the PLLCLK clock, but my set clock does n...
I read that when entering shutdown and waking up through a wakeup pin, the program restarts. If I enter the shutdown in my main method, doesn't that mean that when my MCU wakeup it will restart and then enter the shutdown again in my main method?
