Posted on April 19, 2018 at 22:21Hello, I'm new here and I'm beginner, so I'm asking for your understanding I'm trying to write text on the TFT LCD display using BSP and FreeRTOS, but the string is blurred and pixels are flying across the line. I'm ...
Posted on April 18, 2018 at 12:35I am planning on using the onboard LCD controller on STM32F429. I am newbie in driving TFT LCDs and I have 2 questions:1- I am planning on driving a 800*600 LCD in 24bit rgb mode. This would require a buffer of 1,440...
Posted on April 19, 2018 at 08:10I want I2C function on stm32f103rct.pb8-> sda and pb9-> sclI set ports configuration like this#define I2C_SCL_HIGH GPIOB->BSRR = 0x00000200 //PB9 0x00000200 set PB9 to 1#define I2C_SCL_LOW GPIOB->BRR = 0x0...
Posted on April 19, 2018 at 09:10Hi,I'm working on STM32F407VG board. Try to get USB Host CDC working. I'm able to get enumeration working. The data can be sent to device. But the data is wrong. For example, 'Hello'(48 65 6C 6C 6F) is send from Host...
Posted on April 17, 2018 at 11:56Hi,i have a very strange behaviour on my STM32L433CCTx.Im am configuring the ADC with STM32Cube FW_L4 V1.10.0 to measure multiple channels. As long as i configure 5 or less conversions in the regular conversion group...
Posted on October 30, 2017 at 08:47 Hello, We'rehaving an issue on STM32F765IGT - when trying to use flash on QSPI, configured in 'Indirect mode', using HAL v1.8.0, and DMA enabled. It's quite hard to replicate, but it seems to occur whenth...
Posted on April 19, 2018 at 15:14Dear Community,I want to know (for STM32F407) which DMA streams I can connect to peripheral hardware. From example-codes I know for example that SPI2 interconnects to DMA1_Stream4. The datasheet states: “Each strea...
Posted on April 19, 2018 at 14:35Using CubeMX is was pretty simple to make a USB host for a memory stick. When the stick is connected during power up it works.When the stick is not connected during power up it will work afer calling MX_USB_HOST_Init...
Posted on April 17, 2018 at 10:00Hello , I am using NUCLEOf446re board and i have some issues with TIM3 OC getting 50Kz waveform on channel 1 . when i derive systemclock from PLL . it works fine . systemclock = 180MhzAPB1CLK = 45MHzTIM3CLK = 90Mz pr...
Posted on April 19, 2018 at 14:17So i managed to create files in my SD card yet i can't find a way to read from that file and send it to a webserver until now using the existing example from cubemx i can generate a .html and everything works but i c...
