Posted on April 19, 2018 at 22:25Hi, I have some trouble when I set my PWM to 100% output for my STM32L4 to the input STLD41. I use a 40KHz frequency for my pwm and a periode of 400 cycles. Between 0 to 398 cycles compare everything run smoothly. at...
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...
