Hello,setting up STM32L412 SPI for 16 bit Spi transfer and doing: uint16_t *SPI_DR = (uint16_t*)&SPI1->DR; *SPI_DR = 0;// while (~SPI1->SR & SPI_SR_TXE) {NutSleep(0);} *SPI_DR = 0;results in only 16 bit shifted out. With the check for TXE e...
We have used STM32F429IIT6U in our project . In the beginning , it works fine but after few mins it get stopped. I have replaced the external caps, crystal and controller and also isolated the nearby controller circuit but it is still creating the s...
Hi there! I am actually fighting again i2c communication on the B-L072Z-LRWAN1 evaluation board (STM32L072CZ). Basically I would like to interface a NXP MMA8652 accelerometer over the I2C bus. I was able to do that (get the "who am I" register, get x...
i want to control AC voltage using timer PWM mode ..reference zero crossing signal interrupt every rising edge of zero crossingfrequency of pwm signal (100Hz) some time frequency of AC mains very between 99-100Hz so i need to synchronize my timer ...
Hello, I would like to ask if you can suggest me ST's MCU with peripheral specialized for power electronics controll. I would like to use MCU for PSFB DC/DC converters, three phase inverters, active PFCs and other common power electronics topologies....
Posted on October 09, 2016 at 14:54hello, I've been trying to set up some basic usb comunication with a usb mouse using my stm32f4 discvery. there are no usb examples for my board so I went in to look at other boards. I generated a project with cube...
I know how to do it.AD9288BSTZ has a 8bit parallel interface per channel. If you add a switch, you get ddr mode 4bit. If you use two channels qspi - then the data will be automatically placed in memory in the correct sequence 1-2-1-2-1-2. The theoret...
Hello,Has anyone succeeded in getting the timer cookbook examples (specifically the TIM_ExtCLK_ETR)working on the STM32F303RE? I've been beating my head against the wall for a while now and still haven't seen the light. I'm using the IAR Embedded ...
Hello, I'm trying to run the frequency meter example of App Note 4776 on a STM32F303 Nucleo board. I've built the code specifying the new target. It builds without errors but hangs waiting for the DMA transfer to complete. I'm using the default ve...
Hello,should LSERDY assert with LSEBYP?I have a SIT1533 (32.768 khz Mems ocsillator) connected to PC14/OSC32IN on a L412. I first reset the backup domain, than I enable LSEBYP and with next command I enable LSEON. On a cold start, where the SIT1533 m...
