Hi everyone, I met a problem when I measured the current rms value with stpm33 ic.I'm using this IC with resistive loads and other load profiles with low crest factor. But I met a case with a high crest factor load like as SMPS type loads. I collecte...

Hi, I occur a problem when continuously sending data. I'm working with LwIP_HTTP_Server_socket_RTOS example project in STM32Cube_FW_H7_V1.5.0. (path as STM32Cube_FW_H7_V1.5.0\Projects\STM32H743I-EVAL\Applications\LwIP\LwIP_HTTP_Server_Socket_RTOS). ...

Hi again,I opened a ticket explaining my issue for this error. However, the STM team stated that it’s not possible to resolve this issue with the STPM33. They pointed out that the reason is due to the current signal having a high peak. Based on their...

Its really no problem. Sometimes it can be possible.:thumbs_up:

Hi again Andrew,I am having some difficulty understanding your calculation, specifically regarding how you arrived at the 0.5% figure. If you could kindly explain this to me, I would greatly appreciate it. It is possible that there may be a formattin...

Hi Andrew,Thank you for your reply. It seems that the focus is on the calculated value for the error ratio. However, I don't need the momentary value; I used it only for detecting the error in the RMS readout.Let's focus on the table again, specifica...
