Hello there, I am planning to design an environmental IoT sensor node and i would like to incorporate the SPV1050 IC since it covers my project needs. I did extensive reading of the datasheet and there are some things I would like to get cleared:1. d...

Hello!For a week i've been trying to configure my stm32f302cbt6 and the tlv320aic3254 codec to trasmit data to the mcu through i2s_ext_sd but HAL_I2S_Receive returns 0s to the buffer although i see data coming out of the codec. I have configured i2s2...

Hello!I am trying to configure Master clock output frequency for I2S interfacing with the TI tlv320aic3254 but there is no Master clock or i2s setting on the clock configuration.As i see in the Clock tree in the datasheet there are master clock optio...

Hello,Is it possible to clear out the configuration when load is connected to the cStore pin as stated to the datasheet by forwarding it to the analog department. Is it safe from issues as I stated at the top of the thread? I would like to know that,...

I meant not using LDO regulation. Straight power from battery power while having the uvp, eoc functionality.Btw, i haven't come across any other ics for these applications by st(excepting the SPV lineup)RegardsPatsaoglou P.

Thanks.Looking forward for the update.Few last questions I am curious about:1) Is the 3v3 ldo performance reasonable when there is an Wireless application? Are there any tests made. I started all this discussion because I don't feel LDO can handle tr...

Good morning!Appreciate the fast response! Datasheet states page 5 STORE pin ''Tank capacitor connection pin. Application load, if any, should be connected to STORE or LDOs pins''. That's why I got confused!?So as I described the case above, ldos pow...

Well AScha.3 thanks for the response! Btw for a reason i cant change the send/receive pins from the .iocconfigurator for a reason! i used HAL_I2SEx_TransmitReceive and now i have real time data filling the buffer but i i also had to change hi2s2.Init...
