Re: ESP32 Serial monitor not working

Have you tried adding a delay after Serial.begin, or while (!Serial)?

Timer and PWM issue

This works perfectly the first time toneOn() is executed, after that the ISR is never called. I tried disabling all the ledc* functions to see if there was a conflict, with the same result. Is it ok to call timerAlarmDisable() from within the ISR? Thanks in advance. byte buzzerPin = 12; hw_timer_t *...

Re: Espressif ESP32 Download Tool & Arduino?

Thanks for the comments, and Kolban, of course you're right. I should have mentioned that I'm trying to update users to new versions without giving source code for two reasons - first, I don't want to, and second, that would require them to load the Arduino IDE and build the environment for the ESP3...

Espressif ESP32 Download Tool & Arduino?

Hi All, I've tried the following settings and a few other combinations, but I can't successfully run a sketch that has been exported as a .bin file. They do download to the ESP32 successfully. Settings: SPIDownload @ 0x00000 Crystal Freq: 40M SPI Speed: 40MHz SPI Mode: Tried QIO and DIO Flash Size: ...

Re: BME280 with SPI?

I have no issues with I2C, just SPI. I did manage to get one BME280 working with SPI, but a second one on the bus crashes it. I tried with and without pullups on the CS line. Maybe the cheap sensors don't work well with other devices on the bus. I'm thinking about trying Adafruit or Sparkfun.

BME280 with SPI?

Has anyone tried this? I've tried hardware and software SPI using pins 18, 21, 22 and different pins for CS. I tried switching MISO and MOSI just in case. I tried both Adafruit and Sparkfun libraries, setting both for SPI. I2C works with both libraries. Same setup works with an MKR1000. I'm using th...

Re: RTC

Hi, thanks for the reply.

Is there a similar example for the Arduino core?

RTC

Hi All,

I understand that RTC functions are not yet part of the core. I just want to set and read the time. Would you please point me to an example that directly uses API calls to accomplish this? I haven't found any, at least any that I understand.

Thanks in advance.
