I'm trying to use the internal reference voltage of 2.048V in my application, since I'm powering the microcontroller with 2.8V. But when I select the reference source and enable the VRefBuff with this lines: HAL_SYSCFG_VREFBUF_VoltageScalingConfig(S...
In the datasheet for the TSV711 is sated (p20): 4.8 Macromodel Accurate macromodels of the TSV71x devices are available on the STMicroelectronics’ website at www.st.com.So, where are they??? I looked everywhere, Digikey has a deadlink to the macromod...
I have an application who requires a stable clock source in the whole temperature range but the power budget is tight, so we chose to use the MSI in sync with an external low power 32khz clock.To save extra power we send the core to sleep while it's ...
In the datasheet of the L7987L there is an application schematic for a negative converter (p36), here the VCC is connected to VIN with a 10 Ohm resistor and a capacitor to the generated negative rail (I guess is to filter the power for the low power ...
hi!I found the model for the L7987 (and L too) but it is encrypted for PSpice, but I would like to use this (or any other model for this chip) in LTSpice, exist any unencrypted model for this chip? if not, is there any way to have it unencrypted?
Thanks Uwe!, I didn't knew about this kind of control loop. It makes sense now the variations on the current consumption in a ramp shape.The setup is simple: I routed the MSI to the clock output and connected it to the oscilloscope, in the scope, the...
The odd thing I found about this is the periodicity on the drift, it seems to me like if the low power LDO is not stable at that current. The power supply for the microcontroller is 1.8V, I tried rising it to 3V with a very stable lab power supply, b...
Posted on April 21, 2018 at 18:29I didn't do to much more to this code, but after a while I realized this is a non efficient use of the DMA. I'm sending the data to DMA so it can send the data to I2C, here:HAL_I2C_Master_Transmit_DMA(&hi2c1, 0x78, b...
