Re: listening server
thank you Kolban for your rapid reply. Enjoying your book! I replaced the following line: int sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); with: sock = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); this cleared up the accept error but portqry says the port is not listening. Attempts to connect wit...

listening server
I bought Kolban's book and am using his code example (I added more logging after I ran into problems) for a listening server. int s, r, sock; char recv_buf[64]; struct sockaddr_in clientAddress; struct sockaddr_in serverAddress; static void startServer(void) { /* Wait for the callback to set the CON...

Re: ULP access timer peripherals?
The only clock we have been able to access in the ULP is the RTC slow clock (150khz).
I have not found a way to read the FRC1 from within the ULP. Any ideas?

Looking for ESP32 Developer
Not sure I posted this in the right forum. We are looking for another ESP32 developer to work on our team. This is for a wireless motor control project.

Re: using the SPI flash pins for other things
How do can I configure ESP32 to only use SPI dual (not quad) mode for all flash interface during normal program operation and also configure GPIO 9 & 10 for other use? Is this possible to do on ESP-VROOM-32?

Re: using the SPI flash pins for other things
Sure, we have used up all the GPIO and we need these pins for PWM output for motor control.

using the SPI flash pins for other things
I understand the SPI flash pins can be used as general GPIO. But if there is no flash chip connected, the part will not run an application or even possibly boot. So the flash has to be connected. I assume this means that after the part boots and the program is loaded, then the flash pins can be re p...

Re: ULP GPIO problems
I used a 3.3K resistor to pull it down and measured the voltage. The 2.2K was only a rough visual estimate, I did not make a precise measurement or calculation.

disable external flash on WROOM
Is it possible to send a chip deselect signal to the external flash memory on the WROOM so that some of the GPIO normally used to communicate with the flash chip are available for other purposes?
