I create a custom board to use PT4115 to control LED. This PT4115 can be control with PWM or external DC on DIM pin. According to spec, the DIM range is 0.3-2.5V.I tested the board by I short the DIM pin to GND and the LED turn off.So it show the boa...
First time try ADC Dual Interleaved on STM32H750VB.The problem is when I try to split the 32bit result from DMABuff into 16bit master and slave, some of the reading is zero and it's random. Can anyone show me anything wrong on my code?If disable DCac...
I had using STM32CubeIDE to generate ADC1 single channel with Timer 6 trigger on 1sec. In HAL library, everything work perfectly and I can see ADC interrupt happen exactly on 1sec interval. But when switch to LL library, same project but the interrup...
Thanks peter for your detail explanation. Now I start to know where is the possible problem.I had few more question to clear up:1) Refer to the AN4899 Zener method, is that mean i will need another LDO/regulator to get 5V?2) Your explanation show tha...
Hi,i change as per you say.but it still not working.i measure the DIM pin when toggle the high and low.high = 5V, low = 3.5VHere is my pcb layout.Sorry for all the noob question.
Hi @Community member :I'm using onboard ADC and output to pc so that i can plot out the sinewave in python.here is the graph with wave_LUT: Here is the graph for calsine:All the code exactly the same except one using lookup table and another is calc...
Thanks all, Now I know where is the problem.As for the cache alignment, saw there is no align_32byte on the example in stm32cubeide.they only show :__IO uint32_t aADCDualConvertedValues[ADCCONVERTEDVALUES_BUFFER_SIZE];
