When writing firmware in C for a microcontroller, how can I directly access a memory location such as a hardware peripheral register, given its absolute address? Is there a way to do this safely an...
I am using TPS63000 in my design and I need to control PS/SYNC pin using a micro-controller. **The input to the buck boost converter is 3V to 4.3V which is coming from a battery. The microcontrol...
I want to operate a BLE chip at very close to its absolute maximum voltage. The chip is nRF52810 This is intended for a battery powered device and I want to use a 3.6V non-rechargable battery dir...
I want to design a simple battery charger using MCP73831/2. This chip has a 3-State state pin according to the table below: I have a 3.3V MCU and I want to connect this pin to a GPIO. The MCU is...
Currently, I enrolled myself in a master's course this fall in the field of Computer Engineering. I am excited to create my microcontroller projects. I want to understand how much complexity is exp...
Got a question about hazardous breakpoints in real-time firmware. Does C have a mechanism which lets me mark a section of code such that breakpoints are somehow ignored or not allowed just in that...
I need a Sine Wave Oscillator circuit that can allow me to control its frequency with a microcontroller. Until now all the topologies that I have found if the frequency is changed, a change in the ...
I have an mcu pin and I want to sense a voltage up to 24V to 36V. I want to connect some outputs on the board I'm designing and I don't know whether those outputs will provide a voltage or will be...
I am designing a control system controlled by some microcontroller K: The open loop gain is $G_{o}(s) = \frac{K}{s(s^{2}+4s+3)}$ and the closed loop gain is obviously $G_{c}(s) = \frac{K}{s(s^{...
I have a PIC32MZ2048ECG064, a 64-pin 32-bit microcontroller with 512kB RAM. This is not enough for my purposes, I need to extend it by at least 32MB, preferably 64 or 128. I believe this means I ca...
Background: I have several microcontroller based projects with custom PCB that have been in very-low-volume production, but the quantities are starting to go up. (batch sizes now ~100 and threateni...
Every time I needed CAN, I had just put external crystal and didn't think about it after that. It worked fine. I am wondering however whether the precisions of MCU internal oscillator is sufficien...
There is always a mixed response when comparing power management ICs (PMIC) and microcontrollers in the application of power converters (I mean as pwm controllers). What are the advantages and dis...
Moderator Note If this site were mature, this question would be closed because it solicits opinions, or is too specific about particular models. In the interest of site activity, answers are being...
This is an energy meter reference design guide I found in microchip's website. In a microcontroller how come the registers are specific to the project?Please explain.
When should I consider using RTOS in my application? Every microcontroller has a good number of interrupts then what is the need of it?
I've heard that a bootloader is code that runs on a microcontroller, and is used to get your application code onto the micro. How does that work? Is there anything special that needs to be done to...
I always have a doubt that how do firmware engineers dump code into a quad flat microcontroller? For a starter kit there is already connection like USB or some SPI ,I2C headers to burn the code,als...
