Hi,
I've been trying to solve this problem for quite a while now. I 've get throuth various forum or example projet but nothing do the trick .
My stm32f107 is connected by spi with another microchip (b...
Posted on May 04, 2012 at 15:09After further testing, I discovered that my SPI2 can't send data but SPI is able here's a small table showing the testing result SPI1 SPI2 receive data not able able send data able not able send clock ...
Posted on May 04, 2012 at 10:04Some good news this morning, I was able to read from the slave ! As the CS pin is still low, even at +1V, for the other chip, the signal passed. But there's still nothing passing through MOSI.
Posted on May 04, 2012 at 09:20There's a +0.14V on the other microchip CS pin when nothing is connected. That could prevent the chip select to pass ? The pin I use as CS is the SPI2 NSS. Since I use this periph without enabling NSS output, could it ...
Posted on May 03, 2012 at 16:05 Looks like my chip select don't work that ok after all. I rechecked it ... when i call GPIO_SetBits(GPIOB, GPIO_Pin_12); It's only go up to 1V. It's a 3V output, isn't it ?
