Hello,while using this mcu 16bit adc a strange thing happens.the adc signal is test under a sinusoid signal(0.5Hz from a signal generator), and as shown in the figure at certain level adc keeps unchanged, after leaving this level then the signal incr...

Spoiler HELLO,I have 2 issues1. A bug reportCubeMx generated init code is wrong with LL libthe marco config is not change from HAL to LL2. I cannot enable dual ADC1/ADC2 continous conversion with dma, and at every tranfer finish trigger a intteruptb...

hello, I'm working on ST25DV64KC, especially on FTM mailbox function and EH power supply. Current situation is I need to test maxium frequency avaliable for supplied by EH(STM32L476VGT6 with ST25DV64KC) while communicating through mailbox(FTM). The ...

hi,I made a mistake before, the LM358 is not for generating VREF+ for MCU ADC, it generates ref voltage for INA821IDR, which amplifies the differential signal from sensor.A TL431AIDBZR connecting cathode and ref generates 2.5V reference voltage Vref+...

HI，@MasterT @TDK @STOne-32 I have a hypothsis. The possible cause is that there is a voltage drop of 2-3mV (according to collected data presumably, something equavilent to the diode/transistor drive threshold voltage) exists when comparing the 14t...

HI TDK, I tired fix the 1uf cap today but not work. power supply are generated from LDOs, which is adaptor 12v-> LM1117MPX 5v -> TPS73633DBVR 3.3v -> TL431AIDBZR ADVREF. AGND/GND are tighted through a 0ohm, perhaps I should remove it. But it seems n...

Hi, I have shared my relevant schematics in other replies, please refer to it. I tried two source, one was from designed sensor and amplified and one was directed from a signal generator device. So it is mostly a MCU problem, the chip I'm using is S...
