Posted on March 31, 2017 at 07:05I am trying to get some high speed PWM DMA code working on TIM4 CH3 and TIM4 CH4. I can get theTIM4 CH3 signal on D10 but the TIM4 CH4 on D9 doesn't output anything. Is there some hardware limitation ?
Posted on March 31, 2017 at 03:42mcu: stm32f100vctI am using spi3 and i2c1 together.However, when i2c1 is used, no signal is output from mosi of spi3.If i2c1 is deleted, spi3 will operate normally.If i2c1 and spi1 (remap) are used, I2c SMBA does not...
Posted on March 30, 2017 at 10:51I am programming on nucleo L073RZ board.My target is to jump from the main to the bootloader application without using BOOT0 and BNOOT1 pins.To do that i look over the internet. By using the following video on the in...
Posted on March 30, 2017 at 18:47I see varying information about whether the timers in my STM32F437 are 16 bit or 32. Maybe I missed a table in RM0090 or the data sheet. Could someone please point me to a place where this info might be consolidated?...
Posted on March 29, 2017 at 20:27Hi.I'm using the STM32F746G-Discovery board which has an external 8MByte SDRAM. I've made tests to read the SDRAM by testing to access it by declaring: float *testvar = (float*)0xC0000000; *testvar = 3.4f; disp...
