I'm currently working on an embedded project with stm32f469 microcontroller and trying to communicate with dps368 sensor using SPI communication. DPS368 is operating in mode 3 and now I'm facing an issue where I'm not receiving any data when I'm tran...
I'm designing a unipolar sine wave inverter using a lookup table to generate PWM signals, but I'm encountering some issues and have a few questions:Should the values in the lookup table start from zero, or from the peak value of the sine wave?Is it s...
Hi , In SPWM generation ,in Center align mode ,May i require give one sine table value twice , in the upword and down counting sequence . Original sine wave values: [A1, A2, A3, ..., A200] DMA array: [A1, A1, A2, A2, A3, A3, ..., A200, A200] like wi...
I am using 5 adc values (emg[5]) and can get the value of them. I want to use these values in the main statement, so I assigned it.However I can't get the value. It's always zero. (good[0] = emg[0]) Can I know what's the matter of this,,? Thanks fo...
Hi everyone,For any timer, counter mode is equal to center aligned mode 3/2/1 except for up or down there are phase sub. between pwm channels with different duty values. There is no phase sub channels with same duty values. For example, in TIM1 with ...
I am trying to set up PWM on Channel 1, 2, 3 of TIM3. At first I set up only Channel 1 and the output voltage of PWM is 2.8V. But after I set up the other two channels, the output voltage of Channel 1 & 3 gets to 3.6V, while that of Channel 2 is stil...
Posted on March 03, 2018 at 14:37Hello.I've tried to test sdcard with fatfs on STM32F411RE on NUCLEO-F411RE board.I don't have a compleat 100% sure hardware or software, so I'm struggling to debug if its a software or hardware issue.I've read trough...
Redesign a board with smaller MCU (same family).Want to reuse existing code. Is there a way to update reselect the MCU, update the pinout in iMax, then update the code in the same project? Do not want to start another project for the new MCU.
I am trying to get a 7" LCD to interface with a STM32F407VET6 microcontroller. I am using a display from winstar which the product number is WF70A2TIFGDBT0. The screen is 800x480 pixels and uses 8080 interface. The display uses a SSD1963 driver and I...
Hi,I am trying to communicate with the MPU-6500 from InvenSense and the STM32F405 micro controller in SPI.I managed to read the WHO AM I. And seems to respond well with its value of 0x70.The problem I have is when I want to read the accelerometer and...
