I need to use a postgres lib to communicate my ESP32 to a postgres database. Anyone knows if it is possible to use this lib on ESP-IDF projects? If not, is there any alternative to communicating to a database with ESP32?

It seems like that is only showing on the logic analyzer, the ESP actually receives the right data. I've added the following code xQueueReceive(xQueue, &queuerecv, portMAX_DELAY); queuerecv = ((queuerecv << 8) | (queuerecv >> 8)); buffercirc(queuerecv); if(queuerecv != 33) { printf("It's wrong. \n")...

I'm using Logic16 with 40MS/s.

I'm also using the following pins

Hello everyone, im using SPI to communicate my FPGA to my ESP32, i'm currently sending a stream of decimal numbers (all 33, 16bit transaction), sometimes the data isnt registered correctly, as shown in the screenhot. Seems like the MISO line is not completely stable (?). I'm gonna post my code and t...

Hello, I've ran into some problems while trying to communicate to a FPGA via SPI. After troubleshooting tons of different stuff I went on the internet to research about the SPI frequencies, only found info about highest speed and the rule of the frequency being a number that can be obtained when div...

Hello everyone, I'm trying to develop a code to send data to my PostgreSQL database, I've tried implementing the following database https://github.com/ethanak/SimplePgSQL, using Arduino framework as esp-idf component. Although, when I try to connect it, I get this error: [E][WiFiClient.cpp:266] conn...

Hello friends! Recently I've been trying to figure out how to make my FPGA (master) talk to my ESP32 (slave) correctly. I'm trying to understand how the handshake system works so I can develop a logic inside my FPGA to make it so the CS only goes down when the handshake goes to 0. Does anyone know? ...

What do you mean by extending on the master?

But that setting is for master only. This is the slave!

What do you mean? ty for replying!
