Posted on September 30, 2015 at 08:14 Guys, Can I replace this function SPIPutChar(uint8_t data[]) { /* Write and Read a byte on SPI interface. */ unsigned char inb; /* Wait if TXE cleared, Tx FIFO is full. */ while ((SPI1->SR & TXE) == ...
Posted on October 01, 2015 at 16:03 Hi, I think this would be very easy but I can't get just 1 value from ADC on stm32f4-disco. I configure ADC like this: void ADC_Configuration(void) { ADC_CommonInitTypeDef ADC_CommonInitStructure; A...
Posted on October 01, 2015 at 16:06Hi, I try to use page 6: 0x00040000 (0x20000 128kB) and 0x00060000 (0x20000 128kB) for storing configuration data uploaded via usb interface. The problem is that after erasing single page (using HAL_FLASHEx_Erase )...
Posted on September 30, 2015 at 13:50Hi I am trying to read and write data to the SDRAM. I have used the HAL drivers available on the STM website (STM32Cube_FW_F7_V1.0.0\Projects\STM32756G_EVAL\Examples\FMC\FMC_SDRAM). I can successufully write the ...
Posted on September 23, 2015 at 04:00I'm trying to interface with an OV7725 image sensor. Omnivision has their SCCB which is very similar to I2C but does not generate an ACK bit. It seems like the STM32F407 (and maybe others in the product line, but...
Posted on September 30, 2015 at 15:39Hello, im using TMS32F071RB. I would like to use USART peripheral in DMA without using interrupt, but polling at TCIF. Is that possible? Thanks, M #dma-usart
Posted on October 01, 2015 at 10:58Dear all,I have the following situation:STM32F411CE with PB12,PB13,PB14 and PB15 configured as SPI2 to interface with an external slave sensor.SPI1 (PA4,PA5,PA6,PA7) is used for an external IMU communicating in SP...
Posted on September 23, 2015 at 19:48Hello,I am using STM32CubeMX with F0_V1.4.0 HAL to generate a IAR 7.40 EWARM project.I have setup the STM32F030R8Tx CPU to use the RTC, and generate an internal Alarm A.In the STM32CubeMX I have setup the RTC con...
Posted on September 30, 2015 at 09:15 To start with, I know usart problems are common and I've read lots of threads and other sources trying to find whats wrong but I don't see it. Anyone here see anything to correct? /*Enable USART6 cloc...
Posted on September 25, 2015 at 10:47 Hello, I'm trying to run rs485 using transceiver sn65hvd11, and two 2 stm32f4. The first is a master, second is a slave. The problem is that I cant run the communication between the two devices. This is the ...
