@danadakk,
Periodic wakeups from deep sleep modes is required which seems to be an issue. Cypress only have 1 RTC in deep sleep while multiple timers may be required. Low energy UART is also a factor. Wakeups through interrupts is inevitable.

Hi All,
In 2010, I cam across EnergyMicro microcontrollers while searching for ultra low power controllers for my upcoming projects. Its been 10 years and experience was amazing with different variants of EFM controllers which now belongs to SiLabs.
Thanks for @bobsanjose, for the wonderful...
Hi BigDogGuru and others,
Let me put my question in a different way.
I am currently working on selecting the right development platform my upcoming IoT project. The project is basically an IoT device with Home Access Control features. The device will have capacitive GUI LCD as well. I seek...
Thank you BigDog and Others,
At the moment to avoid complexity in the very start, I would want to go without video streaming and image processing. Only video recording or even image acquisition i.e. low rate jpeg compression will be fine. The suggestion i need is if i still should go for A8 or...
Hi All,
I am firmware engineer. I am planning to make an IoT device for home access control which should support rich GUI with capcitive touch display and affcourse wifi connection for internet. I am also thinking to include a Camera for video recording then playing it on the LCD.
I have...
Thanks everyone.
As per your posts, my previous experience and some search i have short listed following. Few of them are costly. Can anyone suggest some low cost options or even free.

Hi Guys,
I am working on temperature controller for home appliances automation. Using MSP430 as microcontroller. I wan to use touch screen and a facny type GUI for this project. Can i get ideas which software i should use to design/develop GUI and what touch LCDs i can use. The software should...
I know how to use CreateProcess function to run a process or exe. I have a strange issue that my program is being halted somehow during i2c communication. And when i run any test program using Telnet or using CreateProcess command, it start working again.
I am not sure what CreateProcess is...
Keith,
Thanks for reply and i understand the need of polling at higher than 1sec rate. Also i want to detect as you said lack of movements by polling accelerometer data. Right now i am just comparing the current value of one axis reading with previous reading every second to see if there is...
Hi All,
I am working on 3 axis accelerometer application and one of the application is to detect when it is on reset i.e. without any motion. I am polling accelerometer data at 1 Hz and checking it for change in reading to know it is in motion in any axis.
However, the method seems to be very...
Freescale offers ARM Cortex M4 microcontroller with dual speed 10/100 Mbps Ethernet MAC. What is the benefit of that?
Also if a controller like ARM7TDMI from Atmel don't have Ethernet MAC support inbuilt, can we still have access internet to upload the data through tcp/ip.
Where we need ip...
