workaround: error: "floating constant truncated to zero"

hi Mikhail, can you look at the times, please? .. uint8 temper; // result in fahrenheit float celsius; // conversion in Celsius later celsius = ( temper - 32 ) / 1.8 ; .. compile and result without problems in linux and toolchain. compile in windows (minGW) and toolchain and eclipse is possible to g...

ESP32beta Example Code: Blinky with xTask (FreeRTOS)

Sample code for the ESP31B alias ESP32beta hi a simply blinky demo with xTask ( FreeRTOS ) we can mask the gpio too. but this shows the simple things. have used simple api: GPIO_OUTPUT_SET( gpio_no, bit_value ) for your free using: /* * user_main.c * * Created on: 30.12.2015 * Author: rudi ;-) * Fr...

Re: sensor uint8 temperature_sensor_read()

You have a graph of ambient temp accuracy (self-heating effect) over wider range of temperatures? thanks for your interest and demand. this will be the next step, the record with an overview of ambient temp "self-heating" by measuring processing SoC read procedure "self-heating" by measuring with a...

Re: Integrate pre-compiled user libraries

hi not sure how you mean this, ( translater english-german) but think have understand, have a try the bad way would be: put your own lib ( *.a ) in the RTOS SDK Folder \lib and expand the makefile with your libname better way is: create a new own folder and put there your own libs then expand the ma...

Re: jump to run addr @ 0x40000

txs baoshi can confirm this. have not test byself with rigol just in time, but the usb ( 500 mA ) is sometimes short time overloaded and break down. Test with a USB TTL adapter and simultaneous power supply of this was mostly satisfactory. therefore I have made over a USB TTL Adpater the power suppl...

substract 32 from uint8 temperature_sensor_read()

hi think there is a little bug in read function. we must subtract 32 from reading result to get a valid temperature. think there is a mistake in base formula in read function. right working code, this code adjusted by own subtract 32 from the bug [***] // simple code for the measurement of OnBoard s...

Re: sensor uint8 temperature_sensor_read()

Hi think this is the finnish version: be sure you subtract 32 from what is read result by for me this works with a second little calibrate then ( 1 F ) comparatively with a DS18B20. for measurements ambient temperature in which is exposed to the ESP completely adequate, txs espressif! simple code: /...
