Re: NON-OS 1.5.4 (16_05_20) PWM bug

This is not "production" stuff, and for the moment it's not a problem because I can fall back to the older SDK version. But in future SDK versions, I really hope this will get fixed, so I can make use of new features. hi erik not sure - my unthink vision :P 15 min = 15 * 60 = 900 / 6.5 ns...

Re: [HSPI BUG ??] HSPI can we check register for end of hspi transfer, can we mod the CLK

Hello Rudi, As for problem #1, You may want to consider polling bit 18 of the SPI_CMD register. See if it helps with your problem? // Send the data out WRITE_PERI_REG (SPI_CMD(1), (1<<18));SPI_CTRL2 // Wait while transfer is in progress while (READ_PERI_REG (SPI_CMD(1)) & (1<<18)); // Deassert ...

Re: When is SPI MISO sampled?

For the purpose of this post, I was referring to using the ESP as a master. In a recent enhancement to the NodeMCU firmware, we added support for Mode 2 and Mode 3. The MOSI edge (master out, or when the ESP sets the bit from the master) is successfully set using the SPI_CK_OUT_EDGE. However, the M...

Re: We really need a way to differenciate RESET and Wake Up from Deep Sleep

If you have not tried this yet, I would suggest you to look this function up in the documentation of the SDK you are using. You will also find the inf...
