Infineon Integrates Six Industrial Protocols on the XMC7000 MCU

2 weeks ago | allaboutcircuits.com | Arjun Nijhawan

Infineon Technologies and RT-Labs recently collaborated to integrate six key industrial communication protocols directly into the firmware of Infineon's XMC7000 industrial microcontroller. The XMC7000 industrial MCU. With the Industry 4.0 market projected to spike to $862B by 2032, it's more important than ever for industrial devices to support the top communication protocols in this space.

Skywater Technology recently introduced Thermaview Solutions, a suite of read-out ICs (ROICs) and microbolometer solutions for thermal imaging applications. Skywater says this suite incorporates innovations that will support the development of thermal imaging systems using large-format focal plane arrays. Skywater says ThermaView ROICs are scalable and reliable in advanced manufacturing and automation. Image used courtesy of Skywater TechnologySkywater based the suite on its new 90-nm CMOS process.
Silicon Labs Rolls Out ‘Lite’ Low-Power Bluetooth LE SoCs

2 months ago | allaboutcircuits.com | Arjun Nijhawan

Silicon Labs recently introduced its new BG22L and BG24L low-cost Bluetooth chips targeting applications ranging from asset tracking to geofencing. Silicon Labs optimized the BG22L for high-volume, cost-sensitive, and low-power applications while outfitting the BG24L SoC with additional support for channel-sounding technology and AI/ML acceleration. The BG22L and BG24L can be used in asset-tracking applications.
Pressure sensor programme using XGZP6847A001MPGPN sensor

Sep 1, 2024 | forum.allaboutcircuits.com | Arjun Nijhawan |Jake Hertz

Hello Programmers,I'm quiet frustrated now as I'm unable to figure out how I use the XGZP6847A001MPGPN pressure sensor of range -750mmHg to 7500 mmHg using ATMEGA8 chip and ADC 1 channel (10bit adc). I've the setup already and able to get the readings from pressure sensor to display. But dont know how can I limit the pressure within specified range suppose 0mmhg to -130mmhg. Please help me with the formula in C embededd to use.
Inductor design needed

Aug 31, 2024 | forum.allaboutcircuits.com | Arjun Nijhawan

You need an iron powder core, usually a Micrometals #26. You need at least 1.5mH divided by the current (i.e. 1.5mH @ 1A, 150uH @10A), the more the better. Micrometals website has an inductor designer app which has a choice of 50Hz/60Hz filter applications. The iron powder inductor is quite lossy at high frequencies, so dissipates the interference as core loss instead of reflecting it around the circuit. Who still uses filament lamps?
Voltage reversal for 2ms to alow latch release

Aug 24, 2024 | forum.allaboutcircuits.com | Arjun Nijhawan

Hi all I’m having a blank moment today I have a latching pull solenoid that in normal state is latched until voltage is reversed to release I have a 5 volt control tof timer swiching 24v dc to pull the flap down to its latched state but req the voltage to be reversed to unlatch to allow the flap to open again Any ideas on how I can reverse the voltage for 2 ms thinking of using a flip flop relay but my mind is blank ? If anyone has any ideas it will be great appreciatedSimon
Help with Controller for ventilation system

Aug 22, 2024 | forum.allaboutcircuits.com | Arjun Nijhawan

Hey everyone,right now i am tackling the challenge to smartify my dumb house ventilation system, as the original controller is a closed system and often looses connection between master and slave fans. The fans are working in pushing and pulling mode so they can suck air into the house or push it out. I want to be able to control the 3-pin 24V DC Motors that are used in the ventilation system and add them controllable into my home assistant system (preferred would be an ESP32 approach).

It's not the power supply. I bought a new one..still won't come on. Gotta fix it hope it's a fuse.. any ideas. .
differential ampliefier that can convert + or - 10v to 0 to 3.3v

Aug 6, 2024 | forum.allaboutcircuits.com | Arjun Nijhawan

If I understand what you are saying you have a single ended signal that ranges over -10V to +10V and you want to map that o 0-3.3V. You can do it in two steps by first using an attenuation stage with a gain of 0.165 = 20V/3.3V. So +10 V will map to 1.65V and -10V will map to -1.65V. You take this result and add an offset of +1.65V and you have the desired output.
