bcm2835 | Go package for the bcm2835 as used in the Raspberry Pi

I am using ::http::geturl -query to issue an HTTP POST request with a small json payload to an ESP8266 (a 3rd party commercial device) from a rPi. It works when sent over eth0 but fails when sent over wlan0. tcpdump shows that sent over eth0, the message is sent as a single packet but when sent over wlan0 the payload is being split from the headers and sent in a second packet. The ESP8266 most likely due to having overly simple implementation of its packet receivers and/or http server doesn't appear to handle this splitting. It issues a 200 OK response after receiving the packet containing the headers and doesn't process the payload part of the request.

Experimentally I composed the same request message text being sent by ::http::geturl and sent it over wlan0 using nc; it was sent as a single packet and was successfully processed by the ESP8266.

Does anyone happen to know why sending the request using ::http over wlan0 is ending up with this split message, and what if anything can be done to prevent it?

I'm attempting to write to an LCD (LCD1602 Display Screen) using a PCF8574 IO Expansion Board. I've used some example code I found, but although it does flash the background light (so I know it is communicating with the LCD) it doesn't print numbers.

I don't want to use the WiringPI library because it is no longer supported and I want to use the BCM2835 libraries. Anyone know how I can write characters to the LCD? I thought I only needed to send the ascii codes?

I found the only one Python library for the Digital-output relative humidity & temperature sensor/module DHT22: https://github.com/adafruit/DHT-sensor-library

But considering a function in /usr/local/lib/python3.7/dist-packages/Adafruit_DHT/platform_detect.py it's not supporting the latest Raspberry processor (BCM2711):

I'm using the library bcm2835 1, it works, I can see on the terminal how plots 126 data information from a sensor but from that point on I recieve this:

When using py-spidev, if I set the flag spi.threewire=True I get a response similar to this one:

Im a C noob, Ive this code which is supposed to measure body temperature using IR sensor on raspberry pi. The code is working fine but it doesn't work in loop mode and simply prints the temperature only once and exits. While I want it to run continuously until user presses some interrupt key/killed by user.

I am currently working on a program where I need to store big integer values, big enough that they don't fit into uint32. Only int64 or uint64.

I just realized the Raspberry Pi Zero v1.3, that I will be using for this project, has Broadcom BCM2835 processor, which I believe is a 32 bit architecture processor.

It contains an ARM1176JZFS (ARM11 using an ARMv6-architecture core) with floating point, running at 1GHz

How do I ensure my program functions correctly on this 32 bit architecture? Do I have to do anything differently? Or does the compiler is able to handle this without a problem when I cross compile it: env GOOS=linux GOARCH=arm GOARM=6 go build?

I'm trying to show a bootscreen during the boot of my Yocto-build distribution. This runs on a Compute Module 3+ (CM3+). Here's what I figured out so far:

• Compile u-boot with CONFIG_CMD_BMP=y and CONFIG_DM_VIDEO=y
• Place a bitmap image on the boot partition and load it with fatload mmc 0:1 $loadaddr /splash.bmp
• Check that the bitmap was loaded correctly:

Before I write down my problem let me say that I have literally visited all relevant pages on internet regarding RPi4B, SPI, BMI088, bcm2835 library and C, with no luck and a lot of frustration.

I have 6 BMI088 sensors I'd like to connect to RPi4B over SPI. On Arduino it works perfectly (one or all 6) with Bolder Flight library. The problem is I don't get anything from sensor when I connect it to RPi. Connections are ok (3.3 V, GND, MISO, MOSI, SCK, CS, PS to ground (only BMI088)). I also have a switch to turn sensor power ON/OFF. I am sending exactly the same messages as Arduino library does, but I get nothing from the sensor, MISO is silent. I provide a rising edge to CSB1 pin as stated in datasheet. If I connect MISO and MOSI RPi receives data.

How do I get BMI088 to talk to RPi over SPI?
