Posted on March 05, 2015 at 15:12In the typedef for struct SPI_InitTypeDef (in stm32f4xx_hal_spi.h) I find the comment regarding NSS:''Specifies whether the NSS signal is managed by hardware (NSS pin) or by software using the SSI bit. This paramete...
Posted on March 05, 2015 at 14:17Dear friends, please help.I make a touch switch on the 3 buttons. I use microcontroller STM32L151 and its hardware ''touch sensing''.The challenge is to ''touch switch'' with CR2032 battery (225mAh) worked for severa...
Posted on March 03, 2015 at 15:13Hi, before I try myself I would like to ask you whether it is possible to use a timer to start a DMA that reads from the GPIOx_IDR register into a memory location and whether the source would be a peripheral or memor...
Posted on March 05, 2015 at 07:11Dear All, This is Gaurav. I have implemented a STM32F105 based Mass Storage Device wherein I am facing difficulty in Reading Files>2MB from SD Card to PC/Laptop. I have tested with 2 SD Card : Team and Transcend (2G...
Posted on March 04, 2015 at 23:44 I'm trying to use Cube for an STM32F042 project and I'd like the APB1 peripheral clock to be 1 MHz but Cube is saying that the minimum APB1 peripheral clock is 10 MHz. Is this true or is this a problem with Cube? ...
Posted on March 02, 2015 at 16:06Hi, I'm using an STM32F4 Discovery board. I need to send some coefficients from a PC via putty to a digital audio processor (with which I communicate via I2C). I would like to use either one of the USB ports on the b...
Posted on March 04, 2015 at 11:42 Hello ; We are trying to read ADC1 channel 10 with DMA triggered by TIMER2 at 1khz sample , We tried all the compination to make it work but it never words the ADC always read 3,3volt full scale ; ...
Posted on March 04, 2015 at 15:18Hello, I want to read several voltages with the adc of the STM32L051K8. If I convert only one channel, then the value is correct, but if it convert several channel is has an incomprehensible behavior. Sometimes it sa...
