Here some pictures of my first 16 Megabits esp32 infrastructure. Found on retail markets they are between 5 and 7$ CAN, all nude, the caddy, and this one does own two antenna where I can extend it... Apparently they own an SPI / I2C interface to a different frequency and allow simply to be faster. A well this architecture is a whole emulation, and I did not compile heavy-code close to 264 Kilo bytes, I should be safe doing virtual things sometimes playing with Bit/Frequency rather than Kilobyte by screen or sprite. Doing many test with microphone from different amplifier I should have enough memory for working on clarity and many factor bringing reading from sda/scl interface the principle from allocating energy as communication pipes. Apparently esp8266 interface with relay are 3k3 pull-down resistor used to bind a diode and the communication gate with opto-electronic ( mine are 4n35 )switch but relay from the 8 pins interface found on esp-01. I do believe it's not only matter of bandwidth but addressing as well.
Ho, Yes we can start read at it... seems to be 100.41, and temp around 24.4, DHT 22.7, Humidity had pop-up during the snapshot to 39%, and was in %NAN% during the last month, and 15% in the driest of February.
And the question of the day ! If the Astrolab-Base is pointing not in the drive-way but garden, my compas inside the GY-91 device here show about 119.0 Degree, where should be the north in the photo ?
In fact creator of the GY-90 recommend to place the device in your device and bind it with wire not soldering directly. So arduino will be here to interface the transformation of this epic problems of orientation.
My non notorious Wheatstone Bridge equivalent a.k.a. the Arduino Pro Micro (32U4) interface deposed in my GitHub BasicOhmRead_AdaGFX.ino, and BasicOhmRead_ug8 being rewrite to saving in memory by removing uses of the String interaction between the mcu and the SSD1306. I show the back-plane reverse to show some work around direct putting chip on a rag-paper with glue and binding with tin A.W.G. wire, does work, but not using the spot-welder with... without using needle like wire ...
And the Wheatstone Bridge equivalent ; the Shift-register is on the left, while on the right side I do develop addition of operational amplifier the lm358s, with an initial 1k Ohms and 333R3 to promote an rating of 2.5 volts to 10 volts. Actually I feed the Positive branch of the Operational amplifier , but apparently feeding the negative side from the same ratio, will simply reduce the signal to obtain 0V at full force. The force or scale of the voltage here will be sampled by a free Analog pin. The code should already increase the crude voltage from 0 to 5 volts in a already constant measurement of a resistor and do promote of elevate the resistor to much higher voltage level and it's normal if you want by example trigger a resistor configured to raise and flow to a specific voltage adapted to nominal voltage, it's playing with voltage saturation, and old 350 experiments in electronics story of my young times in my bed time and spinning with dazzling detector.
The rest of the story is on my GitHub after i do end some python coding testing micro-python with a PICO a W600, and producing an equivalent to restview I do have to design easy information file easy visible on internet as well tablet and portable. Reducing useless image, restview does help create document in the same as a esp8266 wemos mini and tcs3472 are hard to take as picture, but I develop as well the "AnkaDautreCouleur" and System on chip to read color for a painter in trainning and compare the color on a ocean wide distance. Because it save the information and provide a color comparaison upon selection. And not because you can use your palm or portable to connec on it and see the table of comparaison your employee/trainning crew does by pinning the widget on the wall and pressing the button to query a color-scan.
Here new comer in the family come with official support for STM32 family in Arduino, platformIO, from VScode present on Raspberry PI , I do present an :
- STM32F103C8T6 Blue Pill 64 Kb of Flash and 20 Kb of SRAM at right side .
- STM32F401CDU6 Black Pill in vqfn format own 384 Kb of Flash and 96 Kb of SRAM at left side
It's pretty far from esp32 with almost the same and fewer for S2 and C3, Mega2560 is at 256Kb of Flash, 8Kb of memory, 4 times more than arduino at 32 Kb of Flash and 2Kb of memory.
