There is a link where the tiva c drierlib was utilized on another display…
Part Number: TM4C129EKCPDT We use TM4C129EKCPDTI3R, The POWER indicator light of our equipment is always on when powered by the POWER supply of 3V3, and the POWER supply of the chip is also powered by the POWER supply of 3V3. We use the chip VBAT pin…
Part Number: TM4C129EKCPDT Hi,
We are trying to make MCU interface with 3 LED matrix driver chips. The MCU needs to support 48-bit(16*3=48) long SPI frame (The driver chips are daisy chained on SPI, and every chip is 16-bit wide). When I say 48-bit frame…
Part Number: TM4C129EKCPDT Hi,
JTAG can connect, but has a certain percent that unable to start. Even run to Uboot.
Report NmiSR.
We have tried below methods to recover but failed.
1. Reset it
2. Change a new chip and crystal
3. Check supply voltage, which…

TM4C129EKCPDT-> CAN Tx, also received by TM4C129EKCPDT. It's OK as below right picture.
TM4C129EKCPDT -> CAN Tx, receive it by another brand MCU. It's failed in sometimes as below left picture.
Where should we…
Part Number: TM4C129EKCPDT Tool/software: TI C/C++ Compiler We're using the TM4C129EKCPDT chip.
I want to do that every time the IO port state is changed, the state (variable data of uint32_t) is saved to HIBDATA register (call HibernateDataSet),…
Part Number: TM4C129EKCPDT hi,
my TM4C129 is powered by 3.3V VDD and 3V Vbat, we knew the "battery-backed memory" is powered by vbat, and if calling HibernateDataGet(),, the Vbat is working.
under this situation, if we cut off the VDD, the VDD…

Part Number: TM4C129EKCPDT Dears:
The whole equipment works normally when VBAT pin is powered by CR1220-H (3.0V) and connecting the power supply (VDD3V3/ VDD_MCU in SCH as below);
But disconnecting the power supply(VDD3V3), 1.6VDC is detected on Net VDD3V3…
